Brain tumor grows inside the skull and puts pressure on the brain and gives symptoms depending on the region it is located and the area of the brain it presses. However, as in all cases occupying space in the head, it primarily shows symptoms due to increased intracranial pressure. The brain tumor continues to grow irregularly or regularly according to its character, and the enlargement begins to press on the brain within the skull, which cannot grow.
When a brain tumor is malignant, it can cause other diseases in the body. The brain tumor can be removed by surgery, even if it is benign, it can be followed by a neurosurgeon, or its growth is tried to be prevented by radiation therapy. Brain tumors can be detected completely by chance without any findings. These types of tumors are generally benign and can be detected in cases where there is no reason to have a brain MRI today. Some brain tumors may also manifest according to their size, location and temperament. To list some of the brain tumor signs are headache, severe vomiting, partial paralysis in some parts of the body, personality disorders and epilepsy-like fainting.
Brain tumor usually manifests as benign and malignant. Whether a tumor is benign or malignant is made by examining the abnormal tissue, called pathological diagnosis, with a microscope with some special staining and production techniques. However, with one of the brain imaging methods such as brain MRI, tomography and spectroscopy, the behavior of a tissue can be predicted by looking at the region of origin, whether it is benign or malignant.
As an example of benign brain tumors, meningiomas originating from the cerebral cortex can be given. Meningiomas usually grow very slowly and do not have the ability to spread to another organ. Meningiomas that are small in size and located deep in the brain can be followed up by a neurosurgeon if they do not cause any complaints for the patient. In malignant brain tumors, examples such as glioblastoma multiforme, anaplastic astrocytoma and astrocytoma can be given. The diagnosis of all these tumors should be made by examining the abnormal tissue called pathology with special dyes and a microscope. Pathological diagnosis is made by taking a sample from abnormal tissue by surgical methods or removing it completely. After the pathological diagnosis is made, tumors that respond differently to treatment should be approached in different ways. While some tumors are seen to respond to chemotherapy and radiation therapy for a very long time, there is a possibility that a brain tumor originating from high-grade brain tissue may not respond to these treatment methods. Today, research on treatment methods for malignant brain tumors is still being carried out in many medical centers.
